As many kids, I played a lot with Technic LEGO - starting with the Farm Tractor #851 - when I was young. And, again as many youngsters, I left the LEGO bricks alone as my interest shifted into performing sports (swimming, cycling, quarter triathlons), IT technology education, and having a good time with friends in Clubs and Pubs. After graduating and starting my work-carreer as an IT professional by the #1 Supermarket company in The Netherlands, I slightly developed the thought to restart the Technic LEGO hobby again; . However, it took a couple of years before I turned the thought into practise; actually till the Mobile Crane set #8421 was launched in 2005. I bought this set to figure out what 'step change' LEGO had achieved compared to the Farm Tractor #851.
Well, I was amazed by the significantly improved LEGO Technic parts; providing the ability to design complex technical functions within a model. And given my IT background, I came across the existence of computer aided design (CAD) programs as MLCad, LDview, Lpub and POV rendering. This makes it possible to create your own building instructions in a professional way.
So, I decided to glue things together: At one hand, designing LEGO models based on replica's of existing vehicles, with reliable technical functions and a smooth appearance. At the other hand, show-case the models by leveraging Digital technologies: Create Building Instructions, This website, Social Media and Payments integrations. Let me explain the last one, selling Building Instructions is just to compensate for the effort I made and is all reinvested into LEGO Bricks for the next model or in LEGO sets for my kids. The 'design frequency' for a new model is mostly once a year during winter-time, as free time is the biggest constraint.

For years, my personal 'flagship' was the Prinoth Leitwolf snow groomer (2007), today this is the Cable-system Container Truck (2018). Maybe I should remake the snow groomer with the new LEGO Powered-Up line; I am really impressed what can be achieved with the LEGO Powered-Up 'App', although it has a steep code-block programming learning curve if you are not familiar with IT.
